It's too early to integrate such feature into Similarity, you can always use forum for such task. One imperceptible pitfall of scripting is security reasons on file operations, Similarity doesn't check and can't to forbid what files allowed to read/write and what not. Even without direct access to text files, some hacker can use core file enumerating functional as a security breach.
And this is one of the reasons of new OSX version delay, Apple don't like scripting in the programs (same security reasons) if you plan to distribute via AppStore.
